Type in the Indian Museum, Calcutta. 



This species approaches A. nifirocastaneus^ Burr, and A. glauco- 

 pterus, Borm., but differs from both in the strongly sinuate posterior 

 border of the head, the parallel-sided pronotum, and the longer 

 tarsal segments. 



It also differs in colour. In A. glaucopterus the elytra and wings 

 are of brilliant metallic green-black, with a minute yellow spot at 

 the apex of the latter. In A. nigrocastaneus the elytra and wings 

 are black, the latter having a broad yellow band along the suture. 

 In A. dravidius the elytra and wings are black with a bright 

 orange-yellow spot common to the apex of the elytra and base of 

 the wings ; also the legs ai-e uniform dull greenish brown and 

 the antennae not ringed.
